I actually noticed yesterday that my needle was bent. I do however think it was my fault as I had the carb off and on probably about 20 times. I can say now that I am truly happy with my purchase. At first I had really bad buyers remorse. Spend 3000 on something that wouldnt run right kinda put a damper on things. But now I am extremely happy with my Piranha with the "Genuine Keihin".. It may be genuine, but its not made in japan. Not saying the one made else where isnt good, Im just saying the one made in Japan would be better.. After many hours of time and trial and error I finally got my "genuine" pe28 to run how its supposed to run. Before that the bike was being fixed on more than being ridden. It infuriated me. But I kept to it, determined to fix it. Stock set up was 35 pilot, clip in the middle position, Not sure on the main because it wasn't marked, but I believe they are 120 stock. I put 44 pilot, 125 main, and top clip position on the needle 1 1/2 turns out from seated on the air screw. I know other people had great like with theirs, but mine has just been a complete nightmare. For $104 dollars at JetsRus or any of the vendors here its worth it to just get the japanese version.. But then again maybe the one that you get is perfectly fine. Mine took a lot of time and different jet sizes to get to where I am... whatever you decide, good luck. I hope everything works out great for you.
